New Release Freeze Times

[Mohan Boddu]

Hi all,

It has been brought to our attention that release freezes starting at
00:00 UTC has been confusing for a lot of people. So, we decided to
change it to 14:00 UTC.

The freeze dates are not going to change, just the time when freeze
starts is going to change. Fedora 32 schedule [1] has been updated to
reflect the changed time.
